NissanNismoZ Posted June 28, 2011 Share Posted June 28, 2011 Check the oil? Any noticable damage? If its turning over slower check how many volts you have to the battery.. But thats not why it would just quit.. Did you hear a noise when it did this or did it act like it ran out of gas and had no throttle? If the timing belt snapped, or if you even think it snapped, remove the timing belt cover (top half)and visually inspect it, and check to see how tight it is.. hopefully it didnt snap!

adamzan Posted June 28, 2011 Share Posted June 28, 2011 I would start by putting a new belt on it and see if it runs. If it runs smooth you're lucky but if not you probably bent some valves. Link to comment Share on other sites More sharing options...
1990pathy Posted June 28, 2011 Author Share Posted June 28, 2011 im sure there is bent valves.. cause i tried to start it after it died and there is a tick sound so i think that sound is the piston hitting the valve.. but not sure Link to comment Share on other sites More sharing options...

B have no clue on miles on the belt.. but ive been trying to change the belt for a couple months now but never got around to it because both me and my girl work alot and its our only car,, so i guess i should of done it.. i know the belt says nissan on it,, barely. but it looks very old Link to comment Share on other sites More sharing options...
Kingman Posted June 29, 2011 Share Posted June 29, 2011 Did you post an ad on Craigslist that I responded to for a timing belt repair? If you want to take a stroll on up here to Vancouver, I've got a good set of heads you can have. Not the greatest but maybe they'll get you by until a proper rebuild can be done? They'll need the lifters and rockers put back in. Link to comment Share on other sites More sharing options...

1990pathy Posted June 30, 2011 Author Share Posted June 30, 2011 is there a way to tell if the valves are bent by turning the crankshaft? can you rotate the crankshaft all the way 360 degrees with the cams in the tdc spot?...... Link to comment Share on other sites More sharing options...

I doubt you're going to learn much doing that sort of thing, unless of course you have pieces of valve in your cylinders or something. The engines are barely interference it seems (which is kinda dumb IMHO) so I don't think you can tell much at hand speed. Link to comment Share on other sites More sharing options...

Well, I think that sounds kinda bad... I think with both cams as TDC only cylinders 3 and 5 should have an open valve, so you should still get resistance from most cylinders. I try not to spin the crankshaft without the timing belt on though, so I'm not exactly sure what it would feel like Link to comment Share on other sites More sharing options...

I try not to spin the crankshaft without the timing belt on though, so I'm not exactly sure what it would feel like Its still not easy as you still get compression (or should anyways) on the rest of the cylinders. If the heads are at relaxed all the valves are closed so you can turn it safely. What I mean by relaxed is if you turn the cam gear until it is held in place by the valve springs. You can still turn it but you feel a boat load of spring resistance. At that point the valves are closed enough to safly turn the crank and get it all back TDC. I would relax the heads (you should only need to turn a couple of teeth to get there) and then put the crank tdc then try and time the heads. Personaly I would consider finding a beater while you rebuild the engine/engine swap your pathy. Good luck. Link to comment Share on other sites More sharing options...

sewebster Posted June 30, 2011 Share Posted June 30, 2011 Or I should just buy it if you don't and dump the engine in the river on the way back. Link to comment Share on other sites More sharing options...

ejin4499 Posted July 1, 2011 Share Posted July 1, 2011 im buying it on friday.. and im doing a manual swap, sorry.. tired of the lagging auto trans anyway I didn't happen to see what the listing was. Are you getting another wd21 or are you going to upgrade the engine to a vg33? Kudos on the auto to manual swap. Its not the hardest thing to do but feel free to PM me if you get stuck I just got done doing it myself. Regards ejin Link to comment Share on other sites More sharing options...
1990pathy Posted July 1, 2011 Author Share Posted July 1, 2011 just another vg30(E) but it needed replaced anyway... and ya im pretty mechanically inclined so i should have no issues.. but if i do run into problems ill let you know..and ill post pics of the whole swap...
